13 Troubleshooting
72 YASKAWA TOEPC71061723A YASKAWA AC Drive CR700 Quick Start Guide
Code Name Causes Possible Solutions
oPE01 Drive Capacity Setting Error
The value set in o2-04 [Drive Model (KVA)
Selection] does not agree with the drive model.
Set o2-04 to the correct value.
oPE02 Parameter Range Setting Error
Parameter settings are not in the applicable setting
range.
1. Push to show U1-18 [oPE Fault Parameter], and find
parameters that are not in the applicable setting range.
2. Correct the parameter settings.
Note:
If more than one error occurs at the same time, other oPExx
errors have priority over oPE02.
Set E2-01 ≤ E2-03 [Motor Rated Current (FLA) ≤
Motor No-Load Current].
Make sure that E2-01 > E2-03.
Note:
If it is necessary to set E2-01 < E2-03, first lower the value
set in E2-03, and then set E2-01.
oPE03 Multi-Function Input Setting Err
A function assigned to these parameters conflicts.
• H1-01 to H1-10 [Terminal Sx Function
Selection]
• F3-10 to F3-25 [Terminal Dx Function
Selection]
• H7-01 to H7-04 [Virtual Multi-Function Input]
Set the parameters correctly.
oPE05 Run Cmd/Freq Ref Source Sel Err
The setting to assign the Run command or
frequency reference to an option card is incorrect.
Set the parameters correctly.
oPE06 Control Method Selection Error
A1-02 = 1 or 3 [Control Method Selection = CL-V/
f, CLV] is set, but there is no encoder option
connected to the drive.
• Connect an encoder option to the drive.
• Set A1-02 correctly.
oPE07 Analog Input Selection Error
The settings for H3-02, H3-06, and H3-10 [MFAI
Function Select] and H7-30 [Virtual Analog Input
Selection] overlap.
Change the settings to H3-02, H3-06, H3-10, and H7-30 so that
the functions assigned to them no longer overlap.
Note:
These functions can be set to multiple analog input terminals
at the same time:
• Setting value 0 [Frequency Reference]
• Setting values F and 1F [Not Used]
oPE08 Parameter Selection Error
A function was set that is not compatible with the
control method selected in A1-02 [Control Method
Selection].
1. Push to show U1-18 [oPE Fault Parameter], and find
parameters that are not in the applicable setting range.
2. Set the parameters correctly.
Note:
If more than one error occurs at the same time, other oPExx
errors have priority over oPE02.
oPE10 V/f Data Setting Error
The parameters that set the V/f pattern do not
satisfy the following conditions:
• For motor 1: E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤
E1-04 [Minimum Output Frequency ≤ Mid Point
A Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
• For motor 2: E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤
E3-04 [Minimum Output Frequency ≤ Mid Point
A Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
• For motor 3: E7-09 ≤ E7-07 < E7-06 ≤ E7-11 ≤
E7-04 [Minimum Output Frequency ≤ Mid Point
A Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
Set the parameters correctly to satisfy the conditions.
oPE11 Carrier Frequency Setting Error
These parameters are set at the same time:
• C6-05 > 6 [Carrier Freq Proportional Gain >
6]
• C6-04 > C6-03 [Carrier Frequency Lower Limit
> Carrier Frequency Upper Limit]
Note:
When C6-05 < 7, C6-04 becomes disabled. The
drive sets the carrier frequency to the value set
to C6-03.
Set C6-02 to C6-05 correctly.
oPE18 Online Tuning Param Setting Err
The parameters that control online tuning are set
incorrectly. In OLV control, one of these parameters
was set when n6-01 = 2 [Online Tuning Selection =
Voltage Correction Tuning]:
• E2-02 [Motor Rated Slip] is set to 30% of the
default setting or lower.
• E2-06 [Motor Leakage Inductance] is set to 50%
of the default setting or lower.
• E2-03 = 0 [Motor No-Load Current = 0 A] has
been set.
Set E2-02, E2-03, and E2-06 correctly.
oPE22 Parameter Setting Error
The crane sequence parameter (frequency) setting
error for motor 1.
Set the parameters correctly.
oPE23 Parameter Setting Error
When Vector control, set L7-01 and L7-02 < S1-07
and S1-08 [Torque Limit < Brake Release Torque].
Make sure that L7-01 and L7-02 ≧ S1-07 and S1-08.
